Mussar sobre Isaías 50:9

It is related in Yalkut Shimoni (Esther 1056) that Esther prayed with the words of Tehillim 22, “My God, my God, why have You abandoned me?” This was explained by the holy mouth of the Ari, z”l (Pri Eitz Chayim, Sha’ar HaPurim, Chapter6; Sha’ar HaKavanos, 109b). The idea is that the Holy One Blessed is He in His abundant mercy and lovingkindness supervises and watches over us in order to grant us illumination and to bestow upon us a holy outpouring of the spirit of wisdom and understanding from above, by means of His holy names. Each of these names is an instance of the name “God” — א"ל. The first one comes from the verse, “Who is a God like You?” (Michah 7:18). The second comes from the verse, “Hashem, Hashem, merciful and gracious God” (Shemos 34:6). When this name is spelled out in full [אל"ף למ"ד] it has a numerical value of 185. Thus twice this name totals 370, corresponding to which there are 370 lights illuminating 370 worlds. These in turn illuminate the souls of the righteous departed who toiled constantly in Torah and were diligent in their studies, clinging uninterruptedly to the Torah, which is called “light,” and to the commandments, which are called “lamps.” These two names possess the power to arouse an outpouring of lovingkindness from these 370 lights, which is evoked by the responding of “Amein” with concentration. For whoever responds, “Amein” with intention and also rushes to the synagogue in order to respond “Amein,” merits these 370 lights through his response of “Amein.” On the other hand, if a person despises and takes lightly the response of “Amein,” his soul is met by 370 impure husks, Heaven spare us, which lead him to the chambers of darkness and the shadow of death. Concerning them the prophet declared, “The moth will consume them!” (Yeshayahu 50:9).
